  "message": "[ARM] make page_to_dma() highmem aware\n\nIf a machine class has a custom __virt_to_bus() implementation then it\nmust provide a __arch_page_to_dma() implementation as well which is\n_not_ based on page_address() to support highmem.\n\nThis patch fixes existing __arch_page_to_dma() and provide a default\nimplementation otherwise.  The default implementation for highmem is\nbased on __pfn_to_bus() which is defined only when no custom\n__virt_to_bus() is provided by the machine class.\n\nThat leaves only ebsa110 and footbridge which cannot support highmem\nuntil they provide their own __arch_page_to_dma() implementation.\nBut highmem support on those legacy platforms with limited memory is\ncertainly not a priority.\n\nSigned-off-by: Nicolas Pitre \u003cnico@marvell.com\u003e\n",
